2 Claims. (ores-7.7)

invention contemplates and provides a divided calked sole which is primarily intended to be worn by golfers, but which readily may be applied to a shoe worn by any person requiring,

5 or for any reason desiring, the advantages of shoe calks.

The divided calked sole herein exhibited and described, which is presented as an illustrative embodimentof the present invention, consists of two' suitably calked sole sections of flexible material, which are normally disposed side by side injthe same plane with their contiguous edges disconnected and spaced apart; the extremities of the said spaced sole sections desirably being articulated for relative pivotal movement on Firstly, it is readily adaptable and applicable to shoes having various sole widths;

Secondly, by reason of the fact that the, sole sections are divided and are moved toward'each other when clamped on the fixed sole of a shoe,

the calks of each of the sole sections always lie at the same predetermined distances from that edge of the regular shoe sole with which such particular sole section is associated,-- this re gardless of the width of the, shoe to which the divided calked sole is applied;

Thirdly, because the sole sections are divided and pivotally articulated, they are individually 40 capable of following and conforming to the flex ures of the fixed sole with which they are associated;

Fourthly, the opening between the spaced contiguous edges of the divided sole sections permits the ready escape of any dust, dirt or other foreign matter whichmay find its way between the divided calked sole sections and the fixed sole of the shoe to which they are attached; and

Fifthly, the device of the present invention is of sturdy construction, economical to manufacture, and easy to apply to and remove from the fixed sole of an ordinary shoe.

Other features, objects and advantages of my invention will appear from the following detailed description, wherein reference is made to the accompanying drawing, in which Fig. 1 is a perspective view illustrating the divided calked sole of the present invention applied to the fixed sole of an ordinary shoe;

I Fig. 2 is an upper or interior view of the device of'the present invention;

Fig. 3 is a front elevational view of the device of the present invention, which may be regarded as taken on the line 3-3 of Fig. 2 and looking in the direction indicated by the arrows; the shoes in this figure being indicated by dotted lines; and

Fig. 4 is a fragmentary sectional view taken on the line 44 of Fig. 2 and looking in the direction indicated by the arrows.

Similar characters of reference refer to similar parts throughout the several views.

At 10 I have indicated an ordinary shoe, to the sole ll of which the divided calked sole of the present invention has been removably applied. The said divided calked sole comprises two sole sections 12 and 13, which are formed of a suitable flexible material, such as leather, rubber, tough strong fabric, rubber belting material, or metal which is not stiff and will not readily break under fiexure. In most instances I prefer to employ leather in the formation of the sole sections 12 and13, but the use of any other materials, having the necessary physical characteristics, is within the purview of the invention.

The contiguous edges of the divided sole sections, indicated at 14 and 15, are preferably straight and substantially spaced apart, even when the device of the present invention is firmly clamped'upon the fixed sole of the shoe in the manner presently to be described. The other or outer edges of the divided sole sections, indicated at 16 and 17, are shaped to conform generally to the contour of the edges of an ordinary shoe sole.

Carried by each of the divided sole sections 12 and 13 is a plurality of calks 18, 18, each of the calks shown in the drawing being flanged at 19 to bear against the under side of the sole section by which it is carried, and being provided with a pair of spaced prongs 20, 20, divided to extend through the sole sections and to be clinched against its inner or upper surface, as illustrated in Fig. 4. Each of the divided sole sections 12 and 13 is preferably provided with a plurality of calks located quite closely to its curved or outer edge 16 or 17, as the case may be, other calks being located more closely to its straight or inner edge 14 or 15, as the case may be.

Riveted or otherwise fixedly and permanently attached to the inner surface of each end of each of the divided sole sections 12 and 13, is a metal plate 21, each of which is integrally provided with an upturned clamping portion 22 adapted to bear against the adjacent edge of the shoe sole to which the device of the present invention is applied.

Each of the metal plates 21 is integrally provided with a hollow cylindrical portion which preferably lies opposite and against the adjacent end of the sole sections, 12 or 13, to which the said plate is riveted. The hollow cylindrical portions carried by the plates 21 of the sole section 13 are indicated at 23, 23. They are smooth bored freely to pass the clampingpivoting screws presently to be mentioned. The hollow cylindrical portions carried by the plates 21 of the sole section 12, indicated at 24, 24, are internally threaded to cooperate with the threads of the clamping-pivoting screws. Said clamping-pivoting screws are indicated at 25, 25. While each of these screws has its head slotted to facilitate its manipulation with a screw driver or the like, it will be understood that the heads of these screws may, and often will be, conformed to facilitate the manipulation of the screws with a key or wrench.

The ends of the sole sections 12 and 13 preferably are somewhat oblique to their contiguous straight edges 14 and 15, the axes of the cylindrical portions 23 and 24 and the screws 25, at each end of the device, being correspondingly oblique to the said straight edges 14 and 15. While the degree of the obliquity last mentioned is not a matter of primary importance, it is desirable that the axes of the two screws 25, 25 be parallel to each other to permit pivotal move .ment between corresponding ends of the divided sole sections 12 and 13 as the shoe sole 11 bends and flexes in normal walking or running, or as the result of the engagement of one or the other of the divided sole sections 12 and 13 with a stone, an unleveled surface, or the like.

A calked sole section, within the meaning of this specification and the appended claims, means a sole section which by corrugations, studs or downward projections of any kind is given a non-slip characteristic.

Having thus illustrated and described a preferred embodiment of my invention, what I claim is new and desire to secure by Letters Patent of the United States is:

1. In a device of the class described, a pair of flexible calked sole sections disposed side by side and spaced apart, plates fixedly attached to the ends of said sole sections, shoe engaging clamps formed integral with said plates, a screw receiving portion on each of said plates, one of said screw receiving portions at each end of the device being threaded and the other unthreaded, and a screw extending freely through each one of the unthreaded screw receiving portions and having threaded engagement with the opposed threaded screw receiving portion, said screws serving pivotally to connect said sole sections at their ends and draw them edgewise toward each other to effect their attachment to a shoe, substantially as described.

2. In a device of the class described, a pair of flexible calked sole sections of leather-like material, disposed side by side and spaced apart, plates fixedly attached to the, ends of said sole sections, shoe engaging clamps formed integral with said plates, tension members and means on said plates at each end for receiving said tension members, said tension members being adapted to draw the sections towards each other to bring the clamps into engaging relation with the shoe and being adapted to provide relative pivotal movement between the two sole sections at both ends thereof.
